Q:If I am a good driver, and I never drive far
from home, why should I wear safety belts?
A:You may be an excellent driver, but if you are
in an accident — even one that is not your
fault — you and your passengers can be hurt.
Being a good driver does not protect you
from things beyond your control, such as bad
drivers.
Most accidents occur within 25 miles (40 km)
of home. And the greatest number of
serious injuries and deaths occur at speeds of
less than 40 mph (65 km/h).
Safety belts are for everyone.
How to Wear Safety Belts Properly
This part is only for people of adult size.
Be aware that there are special things to know
about safety belts and children. And there
are different rules for smaller children and babies.
If a child will be riding in your vehicle, see
Older Children on page 44orInfants and Young
Children on page 47. Follow those rules for
everyone’s protection.
First, you will want to know which restraint
systems your vehicle has.
We will start with the driver position.
Driver Position
Lap-Shoulder Belt
The driver has a lap-shoulder belt. Here is how to
wear it properly.
1. Close and lock the door.
2. Adjust the seat so you can sit up straight. To
see how, see “Seats” in the Index.
27

Right Front Passenger Position
To learn how to wear the right front passenger’s
safety belt properly, seeDriver Position on
page 27.
The right front passenger’s safety belt works the
same way as the driver’s safety belt — except
for one thing. If you ever pull the shoulder portion
of the belt out all the way, you will engage the
child restraint locking feature which may turn off
the passenger’s frontal airbag. If this happens, just
let the belt go back all the way and start again.
Center Front Passenger Position
Lap Belt
If your vehicle has a front bench seat, someone
can sit in the center position.
When you sit in the center front seating position,
you have a lap safety belt, which has no retractor.
To make the belt longer, tilt the latch plate and
pull it along the belt.
37

{CAUTION:
Children can be seriously injured or
strangled if a shoulder belt is wrapped
around their neck and the safety belt
continues to tighten. Secure any unused
safety belts behind the child restraint so
children cannot reach them. Pull the
shoulder belt all the way out of the
retractor to set the lock, if your vehicle
has one, after the child restraint has been
installed. Be sure to follow the
instructions of the child restraint
manufacturer.
Notice:Contact between the child restraint or
the LATCH attachment parts and the vehicle’s
safety belt assembly may cause damage to
these parts. Make sure when securing unused
safety belts behind the child restraint that
there is no contact between the child restraint
or the LATCH attachment parts and the
vehicle’s safety belt assembly.Folding an empty rear seat with the safety
belts secured may cause damage to the safety
belt or the seat. When removing the child
restraint, always remember to return the safety
belts to their normal, stowed position before
folding the rear seat.
Regular Cab Models

ready to work for an adult or larger child
passenger.

3. Pick up the latch plate, and run the lap and
shoulder portions of the vehicle’s safety belt
